Types of Swimming Pool Filters1. Sand FilterTypes of sand filters include swimming pool filters that use special sand to purify the water in the pool. How it works from this water filter is quite easy. Water enters the filter tank continuously. then it will spread into the filter.
After that, the water will flow to the bottom of the tube through several layers of sand. Dirt or dust carried by the water will be filtered out, and trapped in the sand. So it will collect in the sand layer.
The filtered water in a clean state will flow back into the pool. With this sand filter, you can filter out dirt or dust with a size of about 40 microns.
After the filtering process, a lot of sand in the sand and filter tube. This will reduce the water pressure in the filter. Therefore, this type of swimming pool filter must be cleaned regularly. How to clean this filter is quite simple. You just have to flip the filter tube, so that the remaining water comes out. After the filter is clean, rinse and then add more sand.2. Cartridge FilterCartridge Filter is a pool filter that uses a paper-type cartridge as the filter media. Generally, this type is used in vertical tubes containing cartridges.
The job of this filter cartridge is to hold dirt in the pool water. With cartridges, the dirt that can be trapped is 10-20 microns, and the volume is smaller than the sand filter can accommodate.
As a result of the filtering process, over time there will be a lot of dirt that sticks to the cartridge and causes the cartridge to become clogged.3. DE filterDE (Diatomaceous Earth) is a type of pool filter that can be used similar to using a cartridge. However, there is the addition of DE powder to the paint cartridge.
It turns out that this powder is a fossil of an aquatic organism called a diatom. When it dies, the diatomic carcass falls and lies on the bottom of the water. DE powder is given to filter feces in small sizes up to 3 to 5 microns.
If you look at it with a microscope, you will be able to see tiny holes that can effectively filter water. Using a complex system, this type of pool filter is considered the most effective and is actually more expensive than other types of filters. However, everyone who uses this type of filter can enjoy the results by looking at the quality of your pool water.4. Media FiltersFilter Media Function is a material that is filled into the sand filter to filter impurities in the water, the filter media can be silica sand or special granular materials that can filter impurities in the water efficiently.
This type of filter is very durable and strong, will not be damaged unless there is an incorrect installation and selection of pump type and current water pressure.5. Pre-FiltersThe function of the pre-filter is to filter 80% of impurities, which reduces the load on the main filter and pump. This filter can save water costs because of the reduced use of water for backwash.
Pre-filter water filter up to 80% before directing water to main filter, main filter does not need frequent washing and can save up to 7000 liters of water every year.
